FIELD OF THE INVENTION

This invention relates to extracts from a plant called Wenguanguo or Xanthoceras Sorbifolia, their uses and functions, and methods of their preparation.

BACKGROUND OF THE INVENTION

Wenguanguo is a species of the sapindaceae family. Its scientific name is Xanthoceras sorbifolia Bunge. Wenguanguo is one of the common Chinese names. The others are Wenguannguo, Wenguanmu, Wenguanhua, Xilacedeng. Its English name is Goldenhorn or Yellowhorn. Wenguanguo can be found growing in Liaoning, Jilin, Hebei, Shandong, Jiangsu, Henan, Shanxi, Shaanxi, Gansu, Ningxia and Inner Mongolia, China. Its seeds, leaves and flowers are edible and have been used as an ingredient in folk or traditional medicine to treat enuresis for centuries. Its branches and woods are also used as a folk or traditional medicine.
Chinese patent applications CN 1092991A and CN 1092992A discussed the methods for producing a medicine from Wenguanguo kernel powder for curing enuresis and enhancing cerebral functions. Chinese patent CN 1052636C discussed a method for producing a medicine with ethanol extract from the Wenguanguo kernel powder for curing enuresis and enhancing cerebral functions. Journal of Shenyang University of Pharmacy (2001), 18(1), 53-56 disclosed the n-butanol extract from the wood of Wenguanguo, which has anti-inflammatory effect.
U.S. Patent Application Publication No. 20030096030 discussed the extracts from the husks of Wenguanguo which are Bunkankasaponin A. B. C. D and two sterols for preventing cerebral aging, improving cerebral functions and curing enuresis, frequent micturition, urinary incontinence, dementia, weak intelligence, and increasing the body's ability to resist the activity of glycosuria.
U.S. Patent Application Publication No. 20030082293 disclosed the extracts Bunkankasaponin A. B. C. D, crude fats, crude protein and sugars from the shell of Wenguanguo.
U.S. Pat. No. 6,616,943, issued on Sep. 9, 2003, discussed the composition comprising Wenguanguo combined extracts and the methods for preparing them and uses thereof. The methods for preparing the combined extract from the husks comprise the following steps: extracting Wenguanguo husks with an organic solvent (e.g. ethanol) to form an organic (e.g. ethanol) extract; removing the organic solvent (e.g. ethanol) from the organic (e.g. ethanol) extract to form aqueous extracts; and drying and sterilizing the aqueous extracts to form the combined extracts. The combined extracts contain saponins, saccharides, proteins and others. The extracts can be used for producing medicines or health foods for preventing cerebral aging, improving memory, improving cerebral functions and curing enuresis, frequent micturition, urinary incontinence, dementia, weak intelligence and Alzheimer's disease, autism, brain trauma, Parkinson's disease and other diseases caused by cerebral dysfunction. The medicines or health foods further comprise Vitamin B, Vitamin D, K, anti-oxidant, Cordyceps or its extracts, gingko or its extracts, Echinacea or its extracts, Huperzine A, folic acid, amino acids, creatine, fiber supplement or a combination thereof.

Cancer cells are defined by two heritable properties: (1) they reproduce in defiance of normal restraints on cell division; and (2) they invade and colonize territories normally reserved for other cells.
Cancers require mutations of many genes to develop, and they are classified according to the tissue and cell type from which they arise. Cancers arising from epithelial cells are named carcinomas. Those arising from connective tissue or muscle cells are named sarcomas. In addition, there are cancers called leukemias, which are derived from hemopaietic cells; and cancers are derived from cells of the nervous system too.
Cancers originating from different types of cells are, in general, very different diseases. Each cancer has characteristics that reflect its origin. Even when a cancer has metastasized and proliferated out of control, its origins can be traced back to a single, primary tumor. Therefore it is important to develop drugs against target cells with a specified character.
Ovarian cancer is the 5th leading cause of cancer death in women and the leading cause of death from gynecologic. In the United States, females have a 1.4 to 2.5% (1 out of 40-60 women) lifelong chance of developing ovarian cancer. Older women are at the highest risk. More than half of the deaths from ovarian cancer occur in women between 55 and 74 years of age and approximately one quarter of ovarian cancer deaths occur in women between 35 and 54 years of age. See MedlinePlus Medical Encyclopedia on ovarian cancer at http://www.nlm.nih.gov/medlineplus/ency/article/000889.htm.
Ovarian cancer is disproportionately deadly for a number of reasons. First, symptoms are vague and non-specific, so women and their physicians frequently attribute them to more common conditions. By the time the cancer is diagnosed, the tumor has often spread beyond the ovaries. Also, ovarian cancers shed malignant cells that frequently implant on the uterus, bladder, bowel, and lining of the bowel wall (omentum). These cells can begin forming new tumor growths before cancer is even suspected. Second, because no cost-effective screening test for ovarian cancer exists, more than 50 percent of women with ovarian cancer are diagnosed in the advanced stages of the disease.
This invention provides compounds extracted from Xanthoceras Sorbifolia or synthesized or other biologic resource or their compositions which have substantial potency against ovarian cancer.

Cells. Human cancer cell lines were obtained from American Type Culture Collection: HTB-9 (bladder), HeLa-S3 (cervix), DU145 (prostate), H460 (lung), MCF-7 (breast), K562 (leukocytes), HCT116 (colon), HepG2 (liver), U2OS (bone), T98G (brain) and OVCAR-3 (ovary).

MTT Assay. The procedure for MTT assay followed the method described in (Carmichael et al., 1987) with only minor modifications. Cells were seeded into a 96-wells plate at concentrations of 10,000/well (HTB-9, HeLa, H460, HCT116, T98G, OVCAR-3), 15,000/well (DU145, MCF-7, HepG2, U2OS), or 40,000/well (K562), for 24 hours before drug-treatment. Cells were then exposed to drugs for 48 hours (72 hours for HepG2, U2OS, and 96 hours for MCF-7). After the drug-treatment, MTT (0.5 mg/ml) was added to cultures for an hour. The formation of formazan (product of the reduction of tetrazolium by viable cells) was dissolved with DMSO and the O.D. at 490 nm was measured by an ELISA reader. The MTT level of cells before drug-treatment was also measured (T0). The % cell-growth (% G) is calculated as:
% G=(TD−T0/TC−T0)×100 (1),

Wenguanguo is a species of the sapindaceae family. Its scientific name is Xanthoceras sorbifolia Bunge. Wenguanguo is one of the common Chinese names; others are Wenguannguo, Wenguanmu, Wenguanhua, Xira Sendeng and Xilacedeng. This plant can grow up to 8 meters in height. It features odd pinnately compound leaf, raceme with white flowers, capsules with thick and woody husks. Wenguanguo is grown in Liaoning, Jilin, Hebei, Shandong, Jiangsu, Henan, Shanxi, Shaanxi, Gansu, Ningxia and Inner Mongolia, China. Its seeds are edible and have been used as a folk medicine to treat enuresis for centuries. Its branches and woods are also used as a folk medicine.
As it will be appreciated by an ordinary skilled artisan, other herbs may replace this particular plant. U.S. patent application number ______, entitled “Composition Comprising Triterpene Saponins and Compounds with Angeloyl Functional Group, Methods for Preparing Same and Uses Thereof” by Chan, et al., filed Apr. 27, 2005, describes the replacement herb strategy. The content of this preceding application is incorporated into this application by reference.
This invention is a further description of the extracts from Wenguanguo, their uses and methods for preparation. This invention provides the extracts that can prevent enuresis by improving patients' cerebral functions so that patients can be more aware of the signals sent from the bladder and wake up from deep sleep. When the bladder is full of urine, the smooth muscle of the bladder is extended, which produces a signal up to the cerebral cortex and cerebellum through the pelvic nerve and the sacral spinal cord. The response of the cerebral cortex and cerebellum to the signal is to make the bladder sustain contracted but the sphincter relaxed. The urine is then discharged. When the bladder is filled with urine via the urethra during sleep, the detrusor stretches, allowing the bladder to expand. As the bladder starts to accumulate urine, it will stimulate the stretch receptors in the bladder that will generate signals continually to the brain according to the amount of urine accumulated in the bladder. When the bladder is full enough with urine, then the intra-vesicle has accumulated enough pressure for the brain to recognize and wake the person to urinate. If the signal is not strong enough to wake the sleeping person or blocked due to impairment of cerebral function, then enuresis occurs. This particular plant extract can cure enuresis by improving cerebral functions.
The sensory stretch receptors are located within the bladder wall and help with assessing the degree of bladder fullness. This information is transmitted up to the spinal cord and then via the spinothalamic tracts to the central nervous system. The extracts of Wenguanguo make the central nervous system more aware of the signal.
When the bladder becomes contracted under stress and nervousness, the capacity of the urinary bladder will be reduced and then the frequent micturition occurs. The extracts of Wenguanguo can relax the bladder for storing more urine.
The capacity of the urinary bladder is reduced because of aging, and this may even happen to middle-aged people. They suffer from experience of early detrusor contraction due to a sense of urgency to empty the bladder at low urine level. The extracts of Wenguanguo can help relax the detrusor and therefore the bladder capacity increases and urinary frequency decreases.
Patients with detrusor over activity, detrusor instability, detrusor hyper-reflexia or uninhibited bladder have early, forceful detrusor contractions before the bladder is full. This creates urgency and frequency urinary discharge. The extract of Wenguanguo relaxes the patient's detrusor. The bladder becomes stable and can store a full amount of urine.
The smooth muscle of the urinary bladder has two functions: When the bladder is relaxed, the urine is stored. When it is contracted, the urine will be discharged. The sensory stretch receptors are located within the bladder wall to assess the bladder's fullness. This information is transmitted up the spinal cord via the spinothalamic tracts to the nervous system. The brain generates inhibitory signals when detrusor relaxation is desired. But the brain generates excitatory signal when detrusor contraction is desired. The extracts of Wenguanguo can relax the bladder tissue by inhibiting Acetylcholinesterase, AchE. The inhibiting effect can be maintained for a long period of time. The extracts of Wenguanguo are a good AChE inhibitor that can cure the diseases caused by deficiency of Acetylcholine, ACh.
Antidiuretic hormone (ADH) is stored in the posterior pituitary gland in the brain. It is the primary regulator of body water. ADH acts on the kidneys to increase or decrease total body water. This has an effect on the volume of urine generated by the kidney. The release of ADH is controlled by the cells of osmoreceptors and baroreceptors. Osmoreceptors are the specialized cell hypothalamus. These cells sense the concentration of particles in the blood. When the concentration of particles is higher, more ADH will be released by the pituitary. This stimulates retention of water to dilute body fluids. When the concentration is lower, less ADH will be released by the pituitary. Baroreceptors are located in the right atria and great veins and carotid sinus the specialized area in the heart that sense blood volume and blood pressure. The heart will generate signals to the hypothalamus and pituitary to release more ADH when blood volume or blood pressure is low and vice versa. The extracts of Wenguanguo can regulate the release of ADH which will reduce the volume of urine produced by the body.

This invention provides a method for preventing cerebral aging, improving memory, improving cerebral functions and curing enuresis, frequent micturition, urinary incontinence, dementia, weak intelligence and Alzheimer's disease, autism, brain trauma, Parkinson's disease and other diseases caused by cerebral dysfunctions, and treating arthritis, rheumatism, poor circulation, arteriosclerosis, Raynaud's syndrome, angina pectoris, cardiac disorder, coronary heart disease, headache, dizziness, kidney disorder and treating impotence and premature ejaculation.
According to the theory of traditional Chinese medicine, enuresis, frequent micturition and urinary incontinence are caused by “deficiency in kidney (“shen”)”. Therefore, they are treated by using Chinese herbs which can tone the kidney, such as Ginseng Bajitian, Roucongrong Duzhong and Cordyceps. These tonifying herbs can strengthen function of the kidney and regulate water metabolism of human's body through the “kidney pathway” that will help with curing the enuresis, frequent micturition and urinary incontinence.
The Wenguanguo extracts of the present invention can also be used to treat the enuresis, frequent micturition and urinary incontinence. However, the Wenguanguo extracts cure the enuresis, frequent micturition and urinary incontinence through the “bladder pathway” to regulate water metabolism of human's body and urination. The Wenguanguo extracts of the present invention stimulate the growth of the bladder. See FIG. 10A. The Wenguanguo extracts of the present invention increase the capacity of bladder and function of bladder controlling the urination. See Experiment 15 and Experiment 15A. In another aspect of the present invention, Wenguanguo extracts, when used with the “kidney pathway” herbs to treat the enuresis, frequent micturition and urinary incontinence, will strengthen both the pathways of kidney and bladder, and then will produce better treatment results.

There are many different periods of sleep a person goes through. These include Slow-Wave-Sleep 1 (SWS 1), Slow-Wave-Sleep 2 (SWS 2), Slow-Wave-Sleep 3 (SWS 3) Slow-Wave-Sleep 4 (SWS 4) and Rapid Eye Movement (REM). SWS 1 and SWS 2 are both periods of light sleep where it is relatively easy to wake someone up. Light sleep is usually more frequent in the second half of sleep. SWS 3 and SWS 4 are both periods of deep sleep, where it is difficult to wake the sleeper. Deep sleep is more frequent in the first half of sleep and each period will get shorter each time afterward. REM is a period of sleep in which people have their most vivid dreams. The wave patterns are similar to the patterns in which a person is awake. However, it is difficult to wake someone up who is in this state of sleep. The sleep cycle of a typical person can be described as follows:
SWS1, SWS2, SWS3, SWS4, SWS3, SWS2, REM, SWS1, SWS2, SWS3, SWS4, SWS3, SWS2, REM. See FIG. 62.
However, the above sequence may not be in a fixed order. The sleep status may shift from SWS 4 to SWS1 or wake up because the body turns from one side to the other. It may shift to the SWS2 status after the movement. The interval between two REM is about 90 min. For healthy people, SWS1 will occupy about 5% of sleep, SWS2 will occupy about 50% of sleep, SWS3 will occupy about 10% of sleep, SWS4 will occupy about 10% of sleep and REM will occupy about 25% of sleep. Since a person in SWS1 and SWS2 can easily be woken, a healthy person has enough opportunities to wake up to urinate. However if a person's sleeping status is mostly in SWS4, he has less chance of waking up when the bladder is full. It is difficult for him to break through the barriers of deep sleep. Then enuresis occurs. This invention relates to a plant extract, including Wenguanguo, for preventing enuresis.
This invention provides the extract of Wenguanguo for inhibiting the uptake of 5-hydroxytryptamine (5HT) in a subject.
5-HT controls and modulates a sleep factor that sustains and increases deep sleep. Inhibiting the uptake of 5HT will decrease deep sleep. People who spend too much time in SWS 3 and SWS 4 are unable to awaken from their sleep when their bladder is full because their sleep is too deep. This is the reason that enuresis often occurs during SWS 3 and SWS 4.
This invention provides the extract of Wenguanguo for increasing the activity of Dopamine in a subject thereby making the central nerve system of said subject alert.
This invention provides the extract of Wenguanguo for increasing the secretion of antidiuretic hormone (ADH) in a subject, which reduces urine in said subject.

There are many components and pathways monitoring cell proliferation.
The compound from Xanthoceras Sorbifolia or its derivatives or metabolites work in the Wnt (Wingless-type MMTV integration site family member) signaling pathway. The Wnt signaling pathway is evolutionarily conserved and controls many events during the embryogenesis. This pathway regulates cell morphology, proliferation, motility and as well as cell apoptosis. It also plays an important role during tumorigenesis. The Wnt pathway has also been observed as inappropriately activated in several different types of cancers in humans.
In the nucleus, the target genes for Wnt signaling are normally kept silent by an inhibitory complex of gene regulatory proteins, e.g. the Groucho corepressor protein bound to the gene regulatory protein LEF-I/TCF. In the absence of a Wnt signal, some β-cartenin is bound to the cytosolic tail of cadherin proteins, and any cytosolic β-cartenin that becomes bound by the APC-axin-GSK-30 will trigger its ubiquitylation and degradation in proteasomes.
The result is the decrease of intracellular amount of β-cartenin. However, when the Wnt binding to Frizzled (a seven transmembrane receptor) and LRP (Low density lipoprotein Receptor) activates Dishevelled (a cytoplasmic signaling protein) by a mechanism, this leads to the inactivation of GSK-β3 in the degradation complex by a mechanism which requires casein kinase I, as well as casein kinase II.
The activity of the multiprotein complex of β-catenin-axin-adenomatous-polyposis coli (APC)-glycogen synthase kinase (GSK)-3β, which targets β-catenin by phosphorylation for degradation by the proteasome, is then inhibited by Dsh/Dvl (Dishevelled, dsh homolog 1). This then inhibits priming of β-catenin, and indirectly prevents the GSK-3β phosphorylation of β-catenin. When stimulated by Wnt, Dvl recruits the GSK-3 binding protein, GBP, to the multiprotein complex of β-catenin-axin-adenomatous-polyposis coli (APC)-glycogen synthase kinase (GSK)-3β. GBP then titrates GSK-β from axin, and in this way, phosphorylation of β-catenin is inhibited. Then, axin is sequestrated by LRP at the cell membrane. The result of all of this is an accumulation of cytosolic O-catenin. In the nucleus, β-catenin binds to LEF-I/TCF, displaces Groucho, and acts a co-activator to stimulate the transcription of Wnt target genes.
The compounds from Xanthoceras Sorbifolia or their compositions regulate the components related to Wnt pathways or its receptors, thereby stopping the proliferation of cancer cells.
The compound or its derivatives work in the Mitogens, Ras and a MAP (Mitogen activation protein) kinase pathway. Mitogens stimulate cell division. The binding of mitogens to cell-surface receptors leads to the activation of Ras and a MAP kinase cascade. One effect of this pathway is the increased production of the gene regulatory protein Myc. Myc increases the transcription of several genes, including the gene encoding cyclin D and a subunit of the SCF ubiquitin ligase.
The resulting increase in G1-Cdk and G1/S-Cdk activities promotes Rb phosphyorylation and activation of the gene regulatory protein E2F, resulting in S-phase entry, in which G1-Cdk activity initiates Rb phosphorylation, in turn inactivating Rb and freeing E2F to activate the transcription of S-phase genes including the genes for a G1/S-cyclin(cyclin E) and S-cyclin(cyclin A). The resulting appearance of G1/S-Cdk and S-Cdk further enhances Rb phosphorylation, forming a positive feedback loop, and the E2F acts back to stimulate the transcription of its own gene, forming another positive feedback loop. Myc may also promote E2F activity directly by stimulating the transcription of the E2F gene. The result is the increased transcription of genes entry into S phase. However if this pathway is overactive, it will cause cancer cell growth.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the Ras-MAP kinase cascade so that the pathway is not overactive.
The compound or its derivatives work in Ras-dependent or Myc pathway. Sometimes the mutation of amino acid in Ras causes the protein to become permanently overactive, stimulating the Ras-dependent signal pathways overactive in absence of mitogenic stimulation. Similarly, mutations that cause an overexpression of Myc promote excessive cell growth, which in turn promotes the development of cancer.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components of the Ras-dependent or Myc pathway to make sure it is not overactive.
The compound or its derivatives reactivate the abnormal cell checkpoint mechanism. Inside the cell, there is a checkpoint mechanism which detects abnormal mitogenic stimulation and causes abnormally overactive cells to go into apoptosis. However this mechanism is not active in cancer cells due to mutations in the genes that encode essential components of the checkpoint responses. If the mutation happens in the checkpoint mechanism, the cancer cell will grow and divide endlessly.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia reactivate the checkpoint mechanism to stop the cancer cell growth.
The compound or its derivatives affect the extracellular growth signaling pathways. The extracellular growth factors that stimulate cell growth are bound to receptors on the cell surface and activate intracellular signaling pathways. It activates the enzyme PI3-kinase, which promotes protein synthesis, at least partly through the activation of EIF4e and phosphorylated S6 kinase, resulting in increased mRNA translation and then a stimulation of cell growth. U.S. patent application number ______; entitled “Composition Comprising Growth Factor of Xanthoceras Sorbifolia Extracts, Compounds Isolated from Same, Methods for Preparing Same and Uses Thereof” by May Sung MAK and Pui-Kwong CHAN, filed Apr. 27, 2005, further describes the growing factor of compounds derived from Xanthoceras Sorbifolia. The content of this preceding application is incorporated into this application by reference.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components or receptor relate to extracellular growth. It binds the receptor of ovarian cancer cells so as to stop the cancer cell growth.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components relating to Ras and MAP Kinase, which ceases ovarian cancer cell growth.
The compound or its derivatives affect the intracellular mechanism. Cell division is also controlled by an intracellular mechanism that can limit cell proliferation. In normal cells, the Myc protein acts in the nucleus as a signal for cell proliferation. Large quantities of Myc can cause the cell to proliferate in excess and form a tumor.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components or receptor of the Myc cell's proliferation to stop the tumor cells from dividing.
The compound or its derivatives affect the TGF-alpha signaling pathway. TGF-alpha is produced by keratincytes, macrophages, hepatocytes, and platelets. Its synthesis is stimulated by the infection by viruses. TGF-Alpha induces the long term proliferation of murine and chicken immature hematopoietic progenitor cell such as BFU-E without causing differentiation. It also induces the terminal differentiation of BFU-Ecell into erythrocytes. TGF-Alpha stimulates the proliferation of cultured endothelial cells. It plays an importance role in the vascularisation of tumor tissues.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components or receptor of TGF-alpha to suppress ovarian cancer and bladder cancer cell growth.
The compound or its derivative compounds affect the TGF-beta signaling pathway. TGF-beta regulates growth and proliferation of cells, blocking growth of many cell types. There are two TGF-beta receptors: Type 1 and Type 2. They are serine-threonine kinases that signal through the SMAD (Protein named after the first two identified, Sma in C. elegans and Mad in Drosophila) family of transcriptional regulators. The TGF-beta pathway and mutation in SMADs are associated with cancer in humans.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components or receptor of TGF-beta to suppress the ovarian cancer and bladder cancer cell growth.
The compound or its derivatives reactivate the cell functions which are damaged by DNA viruses. DNA tumor viruses cause cancer by interfering with cell cycle control Rb protein and the p53 protein. Mutation in p53 gene will allow cancer cells to survive and proliferate despite DNA damage. The papillomanius uses the proteins E6 and E7 to release the p53 and Rb respectively. This action activates mutated cells, allowing them to survive and then divide and accumulate. The accumulation of damaged cells can lead to cancer.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the proteins E6 and E7 and release the proteins Rb and p53, which will prevent abnormal cells from dividing. It also regulates or reacts with the protein, causing the cancer cells to die.
The compound or its derivatives affect the p53 signaling pathway. p53 helps multi-cellular organisms cope safely with DNA damage and other stressful cellular events, stopping cell proliferation in circumstances where it would be dangerous. Cancer cells tend to contain large quantities of mutant p53 protein, suggesting that the genetic accidents they undergo or the stresses of growth in an inappropriate environment created the signals that normally activate the p53 protein. Thus, the loss of p53 activity can be extremely dangerous in relation to cancer because it allows mutant cells to continue through the cell cycle. It also allows them to escape apoptosis. So, if their DNA is damaged, some cells will die but the cells which survive will carry on dividing without pausing to repair the damage. This may cause the cells to die, or they could survive and proliferate with a corrupted genome, which could lead to loss of both tumor suppressor genes and the activation of oncogenes, for example by gene amplification. Gene amplification could enable cells to develop resistance against therapeutic drugs.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia regulate the components and receptor of the p53 pathway, which stops the cancer cells from dividing.
The compound or its derivatives affect the cell suicide signaling pathway. All cells with a nucleus contain various inactive procaspases, awaiting a signal before destroying the cell. Each suicide protease is made as an inactive proenzyme called procaspase. It is usually activated by proteolytic cleavage by another member of the caspase family. Two of the cleaved fragments come together to form the active part of the caspase, and the active enzyme is thought to be a tetramer of two of these two parts. Each activated caspase molecule can cleave many procaspase molecules, which in turn activates more molecules. Through a chain reaction or cascade, this leads to the explosive action of a large number of procaspase molecules. Then, some of the activated procaspases cleave a number of key proteins in the cell, including specific cytosolic proteins and nuclear-lamins leading to the controlled death of the cell.
Activating the death receptor on the outside of the cell can also trigger inactive procaspases. For example, killer lymphocytes can cause apoptosis by producing the protein Fas on the surface of the targeted cell. These clusters of Fas protein then recruit intracellular adaptor proteins that bind and aggregate procaspase-8 molecules. These then cleave and activate one another. The activated caspase-8 molecules then activate downstream procaspases to induce apoptosis.
However in cancer cells, the signal to destroy the cell is blocked, due to gene mutation. This means that the cancer cells continue to divide, thereby causing a tumor.
Compounds or compositions derived from the plant Xanthoceras Sorbifolia unblock the suicide signals, allowing cancer cells to destroy themselves.

Experiment 2: Analysis of Xanthoceras Sorbifolia Extract Components by HPLC Chromatography
Methods.
HPLC. A C-18 reverse phase μbondapak column (Water P/N 27324) was equilibrated with 10% acetonitrile, 0.005% Trifluoroacetic acid (equilibration solution). An extract of Xanthoceras Sorbifolia prepared using the methods described in Experiment 1 was dissolved in equilibration solution (1 mg/ml) before applying into the column. 20 ug of samples was applied into column. Elution conditions: Fractions were eluted (with flow rate 0.5 ml/min.) with acetonitrile gradient from 10% to 80% in 70 min, and then remains at 80% for 10 min. The acetonitrile concentration then decreased to 10% and remained at 10% for 25 min. The fractions were monitored at 207 nm and recorded in chart with a chart speed of 0.25 cm/min and with OD full scale of 0.128.

Experiment 3: Determination of the Cell-Growth Activity Effected by Xanthoceras Sorbifolia Extract with Cancer Cells Derived from Different Human Organs using MTT Assay
Methods and Materials
Cells. Human cancer cell lines were obtained from American Type Culture Collection: HTB-9 (bladder), HeLa-S3 (cervix), DU145 (prostate), H460 (lung), MCF-7 (breast), K562 (leukocytes), HCT116 (colon), HepG2 (liver), U2OS (bone), T98G (brain) and OVCAR-3 (ovary). Cells were grown in culture medium (HeLa-S3, DU145, MCF-7, Hep-G2 and T98G in MEN (Earle's salts); HTB-9, H460, K562, OVCAR-3 in RPMI-1640; HCT-116, U2OS in McCoy-5A) supplemented with 10% fetal calf serum, glutamine and antibiotics in a 5% CO2 humidified incubator at 37° C.
MTT assay. The procedure for MTT assay followed the method described in (Carmichael et al., 1987) with only minor modifications. Cells were seeded into a 96-wells plate at concentrations of 10,000/well (HTB-9, HeLa, H460, HCT116, T98G, OVCAR-3), 15,000/well (DU145, MCF-7, HepG2, U2OS), or 40,000/well (K562), for 24 hours before drug-treatment. Cells were then exposed to drugs for 48 hours (72 hours for HepG2, U2OS, and 96 hours for MCF-7). After the drug-treatment, MTT (0.5 mg/ml) was added to cultures for an hour. The formation of formazan (product of the reduction of tetrazolium by viable cells) was dissolved with DMSO and the O.D. at 490 nm was measured by an ELISA reader [Dynatech. Model MR700]. The MTT level of cells before drug-treatment was also measured (T0). The % cell-growth (% G) is calculated as:
% G=(TD−T0/TC−T0)×100 (1)
where TC or TD represent O.D. readings of control or drug-treated cells. When T0>TD, then the cytotoxicity (LC) expressed as % of the control is calculated as:
% LC=(TD−T0/T0)×100 (2)

Experiment 10: Acid and Alkaline and Enzyme Hydrolysis of Compound Y.
(A) Removal of sugars from compound Y. Acid Hydrolysis of compound Y generates a compound with the following structure, designated herein as Y-c:
(FIG. 37)
Methods: 5 mg of compound Y is dissolved in 3 ml of MeOH and then treated with 3 ml of 3N HCl. Hydrolysis of saponins will be conducted under reflux for 4 hr. After hydrolysis, the solution will be neutralized with 5% Na2CO3 and extracted with Ethyl acetate three times to afford an aqueous layer and an organic layer, containing sugars and aglycon, respectively. Aglycon from the organic layer will be further purified on Silica gel chromatography in (CHCl3: MeOH, 1:9) or with C18 ODS HPLC chromatography. About 2 mg of compound with the above structure Y-c can be obtained.
Method reference: Essentials of Carbohydrate Chemistry. By John F. Robyt, (Springer, 1998).
(B) Partial removal of sugars from compound Y. The linkage of oligosaccharide can be cleaved by partial acid hydrolysis and by specific enzyme hydrolysis. For example, the 1→4 linkage of arabinofuranosyl can be removed by α-amylase. Other enzymes such as β-amylase, isoamylase, glucose oxidase, mannanse and pullulanase can be used to cleave individual saccharide in saponins.

Experiment 11: Extracts X and Y from the Wenguanguo Plant (Xanthoceras Sorbifolia) Improve Learning in Normal Aging Mice.
Extracts X and Y are Different Wenguanguo Extracts
Aging male mice at 16 months of age weighing 35-55 gm were trained in a SMG-2 filled with water 11 cm deep (25-26° C.). The SMG-2 had a start point, 4 blind terminals, the escape platform and their routes. The mice were trained to find the escape platform, and the escape latencies from the water and error frequencies were recorded. After training 3 times, the mice which escaped from the water in 2 minutes were selected for the test. The selected aging mice were divided into 9 groups of 11: 1) control: receiving normal saline (NS); 2) Positive control: receiving Xi-en-kai 0.9 g/kg; 3) X-I group: receiving 100 mg/kg4; 4) X-II group: receiving 200 mg/kg; 5) X-III group: receiving 400 mg/kg; 6) Y-I group: receiving 125 mg/kg; 7) Y-II group: receiving 250 mg/kg; 8) Y-III group: receiving 500 mg/kg and 9) model group.
All the drugs were received through oral administration, 20 ml/kg, 3, 6 and 9 days before the water maze test. The escape latencies (EL) from the water and error frequencies were recorded. All data were analyzed with t-test.

11.1. After 3 days of administration of extracts X and Y from Wenguanguo Plant, hereinafter as “X” and “Y”, respectively, the escape latency in the water maze by the group 9 mice receiving 500 mg/kg of Y decreased significantly compared with the control (P<0.05). The other dosage treatments showed improvement too but not significant ones. See Table 11.1.

Experiment 13: Effects of Extracts X and Y on Improving Impairment Induced by Scopolamine Hydrobromide in Passive Avoidance.
ICR mice weighing 16-20 gm were trained in a STT-2. A mouse was placed on the platform and the SDL were recorded. When the mouse stepped down and all four feet were on the grid, it received electric shock (36 V) immediately, and the EL was recorded. The mice with SDL and EL within 2-60 seconds were selected for the test. The selected aging mice were divided into 9 groups. Each group had 5 male and 5 female mice. All the drugs were received with oral administration, 20 ml/kg, 3, 6 and 9 days before the platform training. The SDL, E1 and error frequency (the times of receiving electric shocks) made in 5 minutes were recorded. After 10 days of administration all the groups of mice received Scopolamine hydrobromide by injection, 3 mg/kg. After 30 minutes of administration of Scopolamine hydrobromide the mice were trained on the platform and the training was repeated the next day. The performances of the mice in the training were recorded. The SDL, EL and error frequency were recorded. All data were analyzed with t-test.

Experiment 14: Effects of Extracts X and Y on Improving Impairment Induced by NaNO2 in Water Maze Learning.
ICR male mice weighing 16-19 gm were trained in a SMG-2 filled with water 11 cm deep (25-26° C.). The SMG-2 has a start point, 4 blind terminals, the escape platform and their routes. The mice were trained to find the escape platform, and the escape latencies from the water and error frequencies were recorded. After training, the mice which escaped from the water within 1 minute were selected for the test. The selected aging mice were divided into 9 groups of 11 mice. All the drugs were received with oral administration, 20 ml/kg, 3, 6 and 9 days before the water maze test. After 10 days of administration all the groups of mice were received with NaNO2 by injection, 120 mg/kg. After 24 hours of administration of NaNO2 the mice were trained to find the escape platform, and the escape latencies from the water and error frequencies made in 2 minutes were recorded. The administration of pentobarbital sodium continued for 3 days and the performances of the mice in water maze test were recorded. The escape latencies (EL) from the water and errors frequencies were recorded. All data were analyzed with t-test.

Experiment 15: Effects of Wenguanguo (Xanthoceras sorbifolia) Extracts on Urination in Mice.

As used herein, Extracts (or Fractions) X and Y are different extracts of Wenguanguo plant or Xanthoceras sorbifolia.
Methods of Experiment. One hundred twelve male ICR mice weighing 18-22 gm were divided into 8 groups of 14: 1, control: receiving normal saline (NS); 2, DCT group: receiving DCT 33.4 mg/kg; 3, X-I group: receiving 100 mg/kg4; 4, X-II group: receiving 200 mg/kg; 5, X-III receiving 400 mg/kg; 6, Y-I group: receiving 125 mg/kg; 7, Y-II group: receiving 250 mg/kg and 8, Y-III group: receiving 500 mg/kg.
All the drugs were received with oral administration, 20 ml/kg, once a day for 3 days. After the last administration, the mouse was placed on a filter paper. The filter paper was on the bottom of a 500 ml beak. The quantity of urine was measured at 30, 60, 120, 180, 240, 300, and 360 minutes by weighing the filter paper with the electronic analytical scale. All data were analyzed with t-test.
Results. After 3 days of administration of X and Y the quantity of urine discharged at 30 minute by the mice receiving 400 mg/kg of X decreased significantly (P<0.01) compared with the mice receiving normal saline. The quantity of urine discharged at 60 minute by the mice receiving 600 mg/kg of Y decreased significantly compared with the mice receiving normal saline (P<0.01).

The quantity of urine discharged at 180 minutes by the mice receiving 200 mg/kg of X, 125 mg and 500 mg/kg of Y decreased significantly compared with the mice receiving normal saline (P<0.01). See Table 15.1.

Conclusion. The results indicated that the extract X and Y can regulate the quantity of urine after 3-10 days of administration of X and Y.
Experiment 15A: Antidiuresis Test of Rat in Metabolism Cage.
The antidiuresis tests using Xanthoceras Sorbifolia Extract FS(X) and Xanthoceras Sorbifolia saponin extract FS(Y) were carried out in rats. Note: Extracts FS(X) and FS(Y) similar to Extracts X and Y respectively. FS(Y) and FS(X) are crude saponin extracts and the “FS(Y)” and “FS(X)” are the extract names that were used in the experiments.
SD rats were treated with FS(X) by oral administration, daily at the doses of 100, 200, 400 mg/kg for 25 days. The experiment included a negative control group and positive control. Collecting urine in Standard metabolism cage and observation indicators, including urine volume, urine Na+, K+, Cl− content, pH and osmotic pressure. The results obtained were as follows: (1) Extract FS(X) has dose-dependant antidiuresis effect. There is significant antidiuresis at all the time phases for 200 and 400 mg/kg. However, by urination rate, the 400 mg/kg dosage group has a more significant effect in that it can delay urination output by two hours. In addition, there is no change in the impact on total urine volume output. (2) The extract FS(X) increased the concentration of ions in urine after drug treatment. However, there is no apparent dose dependency. (3)FS (X) and FS (Y) have no significant impact on the pH value and osmotic pressure, but have slight impact on the specific gravity.
Objective. Standard metabolism cage method was carried out in rats to research the antidiuresis of FS(X) and FS(Y).
Test Drug. FS(X) is compositions of Xanthoceras Sorbifolia extract. FS(Y) is compositions of Xanthoceras Sorbifolia extract. The test drug is a suspension formulated with 0.5% sodium carboxymethyl cellulose (0.5% CMC-Na).
Test Animals. Male SD rats, initial weight 150-200 g, 100 individuals. The test animals are raised in cages (volume: 20×30×45 cm), and each cage has 5 animals. The basal feed is the full-rate pellet feed for experimental rat, self-made by the Experimental Animal Center. The cage bottom padding is wood shaving and chaff, dried before use. After the padding replacement that is made every other day on average, the cages are disinfected before reuse. Laboratory temperature 23±2° C., humidity 40˜70%, with air-conditioning, exhaust and ventilation equipment, natural lighting and a light-shade cycle of about 12 hours.
Animal Screening. The animals are placed individually in the cage for adaptation once a day for 6˜10 hours per day for 2 days. Before placing them into the case, press the lower abdomen gently to discharge the remaining urine, inject 38° C. distilled water into the stomach at the volume of 25 ml/kg as the water load. Collect the urine in the metabolism cage within 2 hours after stomach injection; collect the remaining urine by pressing the lower abdomen gently immediately before taking them out of the cage. Animals whose urine volume attains above 40% of the injection volume will be qualified ones.
Test Instruments. Standard metabolism cage, Automatic urine analyzer (Miditron Junior II), Urine osmotic pressure tester, and Urine ion tester (EL-ISE, Beckman).
Methods
Test groups. There are 3 groups for the FS (X), i.e., for 100, 200, 400 mg/kg/day, respectively. There is a dosage group for FS (Y): 400 mg/kg/day; once a day, fed at 30 min after administration, for 25 days. Control group were fed with 0.5% CMC-Na into the stomach every day. The positive control drug is pituitrin, injected into the abdominal cavity at the rate of 0.25 u/kg before the animals are placed in the cage. Each group includes 10 animals.
Urine collection and observation indicators. For the test groups, the animals that have experienced the administration period are on diet for 18 hours before urine collection without prohibiting drinking. After pressing their lower abdomen gently to discharge the remaining urine, apply the water load of 38° C. distilled water at the volume of 50 ml/kg, and place them in the cage for urine collection. Collect the urine volume and times at 0.25 hr, 0.5 hr, 1 hr, 2 hr, 3 hr, 4 hr, 5 hr and 6 hr after water feeding, when the animals are taken out of the cage at 6 hr, press their lower abdomen gently to collect the remaining urine in the bladder. Conduct the routine urine examination (pH, erythrocyte, leucocyte, protein, etc); measure urine Na+, K+, Cl− concentrations and urine osmotic pressure for the urine samples.
Data processing. Urination speed, Relative urine volume, Urine Na+, K+, Cl− content data are shown in X±Sd, and are compared with the control group and subject to a student t-test.
Results
Impact on urine volume. FS (X) has dose-dependant antidiuresis effects. There is a significant antidiuresis effect at all the time phases using dosages of 200 and 400 mg/kg. See Table 15A-1, FIGS. 63 and 63A. However, by urination discharge rate, the 400 mg/kg group has a more significant effect in reducing the urine output during the first 2 hrs as compared with the control. See Table 15A-2, FIGS. 64 and 64A. The FS (Y) 400 mg/kg group has an equivalent drug efficacy to FX (X) 400 mg/kg during the first 2 hours of experiment. In addition, there is no apparent dose dependency in the impact on total urine volume during the whole experiment. The 400 mg/kg groups of FS(X) can significantly reduce the urine volume during the first 6 hours after the drug-treatment which is more effective than the positive control drug (pituitrin).
Impact on Na+, K+, Cl− ions in urine. By reducing the urine volume, the test drug has increased the concentration of ions in urine to different extent. However, there is no apparent dose dependency. By ionic, there is almost no impact on Na+ and Cl− ions, there is a certain discharge promotion action on K+ ions. The concentration and discharge amount of all ions in urine from the positive drug have risen apparently. Impact on urine pH and osmotic pressure. FS (X) and FS (Y) have no significant impact on the pH value and osmotic pressure, but have slight impact on the specific gravity.
FIGS. 63 and 63A, Table 15A-1, shows results of the urine volume with water load after FS(X) Xanthoceras Sorbifolia Extract administration for 25 days. FIGS. 64 and 64A, Table 15A-2, shows results of discharging urine speed with water load after FS(X) Xanthoceras Sorbifolia Extract administration for 25 days.
